Once you set up these custom usernames, each time someone tries to register to your WordPress blog site providing this targeted username, the registration process is getting bailed and the user gets error message..

Before digging into details about this one, email service provider is the website that follows @ in the email address.

example is adding outlook com to ignore all registrations using email address ending in @outlook com.
Custom error messages You can set up custom error messages so that the users trying to register and getting bailed will then know what the issue is and what to do for better experience...
